To all whom it "may concern.

lie it known that we, l lnwann M. liouAN and (hhuucxcn l l\l.c N.-xucu'ron, citizens of bers a and transverse end dlate members a o.

thellnitcd States, residing at Sonyea, in the county ofliiviugston and State of New York, have invented a new and useful Imr a r prov emcnt in lurn-lables and l ower- 'lransmission Mechanisms for Motor-Vehicles, of which the following is a specification. This invention relates to turntables and power transmission mechanism which are intended for use with motor propelled vehicles. H The object of this invention is to produce a practical and desirable turntable for motor propelled vehicles, which is of inexpensive and simple construction and is operated by power .supplied by the vehicle which isbeing turned, and further 'to provide means whereby the motor vehicle can also be utilized. for operating other machinery.

H In the accompanying drawings: Figure l is a sectional side elevation of a turntable embodying'the invention showing a motor vehicle in place thereon. Fig. 2 is a sectional side elevation on line 2--2, Fig. 4. Fig. 3 is a fragmentary sectional side elevation on line -3--3, Fig. 4. F ig.'-lisa fragmentary plan view of the turntable. Fig. 5 is a fragmentary sectional elevation on line 5-43, l ig. 4. Fig. (3 is a fragmentary plan view on line (3G, Fi 5. Fig. 7 is a fragmentary plan view of an attaching m mus for the vehicle chassis. .Fi 8 is a sectional view of one of the pulleys.

Like reference characters refer to like parts inthc several figures, The turntable A is pre'lerabl y arranged to turn in a suitable pit'P). This turntable may be of any suitable construction; for instance, as shown it comprises a circular top or platform a and a supporting rectangular frame composed of parallel longitudinal side meniand interme- To this frame are secured suitable wheels a which rest and are adapted to travel on a circular track arranged in the pit for rotatably-supporting the turntable.

C C represent pulleys which are seen fed on parallel shafts c c suitably journaled onthe supporting frame of the turntable lee-- ncath the platform (a and which are adapted to support the driving wheels of a motor vehicle as shown. in Figs. 1. and 3 and be driven thereby. Each pair of pulleys G C is connected by a belt (7 so as to provide a greater frictional surface for the driving wheels of the vehicle and insure better traction.

Motor vehicles with which the present apparatus is intended to be used are ordinarily equipped with pneumatic tires having treads of substantially semicircular cross section, and when the driving wheels of such vehicles are placed upon the belts (Z as shown in Fig. 1 the weight of the vehicle together with the shape of the tire will cause the belts toconform more or less to the face of the tire or assume a concaved or trough shape. By reason of this the machine belts of the ordinary kind will gradually creep off the leys. To prevent this creeping of the belts each pulley C 1' is preferably provided with a centrally arranged peripheral groove d adapted to receive a longitudinal projecting rib (Z on the inner face of the belt (Z. The curved tires bearing on the middle portions of the belts hold these ribs in the grooves of the pulleys and thus prevent the belts from shifting on the pulleys. notwithstanding the lifting of the edge of the belts. The pulleys are also preferably provided with side flanges between which the belts are confined. The platform (I, is preferably pro vided with tracks or rails 15 of any suitable kind for guiding-the driving wheels onto the belts (Z when the motor vehicle is run onto the turntable. I

As shown. the pulley shafts c c are joun naled in bearings c and c which are secured on the side members 0 of the supporting frame and on longitudinal frame members located between the side members. The bearings 1: of one of the shafts c are all-- justable on the frame toward and from the other shaft so as to tighten or loosen the belts (Z or to increase or clecr ase the distance between the pulleys to accommodate driving wheels of diil'erent sizes. This adjustment is effected by means of adjusting screws connecting the bearings c to the-end of the sumiorting frame.

In Fig. 1 an automobile is shown in place on the turn-table with its driving wheels resting on the belts connecting the pulleys C C. If the drive wheels are driven by the vehicle motor with the vehicle in this position, the pulleys and the shafts c c to which they are connected will be driven by the fricpul- ' from the supporting frame and is connected by a beveled pinion h and gear wheel 72/ to the shaft of one of the supporting wheels a for the turntable. The shaft G isdriven by a pinion i and a gear wheelI connecting it to the shaft 0. The gear wheel I is splined on the shaft 0 so that it can be moved endwise to place it into and out of mesh with the pinion 71. By shifting the gear wheel I into mesh with the pinion i the shaft G can be driven for moving the turntable to turn the automobile to face in any desired direction, while by throwing the gear wheel I out of mesh with the pinion 2' the motion of the turntable can be arrested and the mecha- I nism can be utilized for transmitting power for any other desired purpose. The gear wheel I can be shifted by anysuitable means,

a lever K being shown for this purpose which is located in a convenient position on the turntable and is connected by a rod It" to the gear wheel 1. Any other known or suitable means can be employed instead of the shifting gear for connecting the shaft G to and disconnecting it from thedrive shaft 0.

L represents a brake adapted to prevent the undesired rotation of the pulleys C C and to hold the pulleys so as to provide a rigid traction surface to the driving-wheels of the motor vehicle while the vehicle -is being placed on or removed from the transmission mechanism. A brake or stop device of any suitable kind may be employed. That shown is pivoted on the supporting frame and has a shoe adapted to engage one of the pulleysC and is connected to an operating lever which extends up through a hole in the turntable. A suitable device, such as is shown in Fig. 3, is preferably provided for holding the vehicle with the driving wheels in place upon the belts. As shown, this device consists of a bar Wt to which are pivoted hooks n n. The hooks n n are adapted to be hooked over the rear axle housing of the vehicle and fithebar m is adjustably secured in a clamp 0 secured to the frame member 7). When the "hooks n n are in the desired position the bolt 0' can be tightened so as to secure the bar we and thus securely hold the vehicle in place.
